About it 2 seconds after it disappeared I thought I heard a very faint boom, but I cant be certain it was from the object. This is a very populated area so it could have easily been unrelated.
Persistent train

-1s

It was dark out, so I\'m not sure if it had a train.
Terminal flash

It seemed like it got a little brighter as it approched the horizon. I\'m not sure if it qualifies as a \"flash\", but it did get a little brighter before it disappeared.
